To all whom ibm/ny connerie:

Be in knownl that I. .lnnns-,gynnsnnrnn e eitizen'of thelUnitedStet'esresiding et Bualo, in thecountyof Erie and State of New Yorkrheveinvented e new and useful Improvement in Apparatus for Repairing AsphaltPeyegients, of which the followingv `1s e specification.

This invention relates to theportebe heetnv ingdeviees which are usedfor Vmelting or softening the surface of'esp'helt 'peveznent inrepairing the same.-

Heretoforeen apparatus joonsisting of e series of hydrocarbon burnerssupported upon o a. Wheeled freine `in close proximity to the surfacevof the lpa'venientyghes' been employedfor thispurpos'e,bntthisiappajretfus :is objectioneble beoansethe naines' nemingAineenteet with the parlementaire liablepto burn the surface before theparticles below the surface are suiieiently softened. Such burners alsoheat the pavement nneven1y, the` portions there-oi in e'ontaet iriththe`Heines being soft ened 'to a' greeter'degreethan the intermediateportions.V Furthermore, the nep'htha con Itsined in the hydro-carbonfuel'ernmble's or disintegrzites the snrfaoe of `the pavement 'whenbrought in `eonteot therewith, so that leakage of the earners is liablevto 4render the work defective.

The object of my invention is :o provide an npperetulsl whereby heetthey be uniformly applied to the surface of the pavement withontliability of burning it, and which permits the use of fuel that is freefrom the objections of hydrocarbons.

In the accompanying drawings consisting Ot' two sheets: Figure 1 is aside elevation of my improved'epperets` Fig. 2 is e top'pvlenviewthereof. Fig'. B is e cross section of the same in line 3 -3, Fig.l, looking rearward. Fig. 4 is n. bottomplen View of the fuel basket.Fig. 5 is aan enlarged. section al elevation of thesteeringwheelanditssupportingfreme. Fig. l6' is an enlarged crosssection of one of theoperating shafts of the fuel basket showing themeans of connecting thesus'nension chains thereto.

Like lenters of reference refer to like parts in the several. gnres.-

Dis e handle or lever connecten wim the for-kof the steering wheel by nyoke D2.

E is s fuel basket or receptacle suspended from the portable supportingfreine between the front end rear wheels thereof and.' adapted tocontain a bed of incandescent eolie or simi- This basket is preferablyof the oblong form shownin the drawings and is. provided with a.perforated or retiouleted bottoni to permit the radiation of the burningfuel through the seme. lts side end end Walls are also preferablyperforated or retieuleted to supplynir to the l'nel` on all sides.

ln the construction shown in the drawings the-fuel basket consists ofhorizontal rectanguler top and bottom frames e e connected et thecorners by vertical angle pieces e2, a. bottom of wire elothseeured tothe Vbottom freine of the basket and side and end walls of wire clothsecured to the top and bottom frames, the meshes'of the Wire cloth beingsuleiently small to prevent the fuel from dropping through the seme. Theframes of lthe basketare preferably constructed of angle iron, es shown.o

e3 represents transverse bersV extending across the `Wre cloth bottom ofthe fuel baskei: and secured' at their ends to the side members of thebottom frame e'. These bars prevent sagging of the bottom under theWeight of the fuel and also stien the bottom frame ofthe basket. Thefuel basket is snspene from the portable snpporting fremeoy ehsins or'sables T IDO which are secured/at their upper ends to transverselshafts G, preferably by eye bolts, as shown in Fig. 6. These shafts turnin bearings formed in the side bars A and each ofthe same is provided atone end with a crank g for turning it, and a ratchet wheel g with whichenA gages a delent g2 pivoted tothe adjacent side bar whereby the shaftis held against retrograde movement. The chainsF are provided at theirlower ends with hooks f which engage with perforated hangers 7i. securedto opposite sides of the fuel basket near the ends thereof. The basketis supported by ,four chains, two near each end thereof, and the twochains at the same end of the basket are connected with the sameoperating shaft.

In using my improved apparatus, the basket is first filled fromend toend with burning fuel, preferably coke, forming a solid bed which isexposed both on the bottom and the' sides ofthe perforated basket. Theapparatus is then moved' to bring the fuel basket over the spot to berepaired and the basket is lowered with its bottom in close proximity tothe surface of the pavement.A The heat ra` diated from the bed of fuelthrough the perforated bottom Iof the baskety in a short time softensthe pavement sufficiently to permit itl to be raked or agitated. Thenecessary quantity of fresh asphalt is next added, and after .removingthe apparatus the vrepaired. spotis smoothed and burnished by the usualappliances. The supporting shaftsand chains of the fuel basket permitthelatter to be ad- "usted vertically for lowering it into a depression ofthepavement or raising it clear of a ridge, in moving it from place toplace. ,As the heating medium consists of a solid bed o f fuel, thedefective spot under treatment is subjected to a practically'uniformdegree of heat throughout the area of the basket,'sot'tening allportions thereof evenly and insuring a complete incorporation of the oldand the new material. The burning fuel l through which the lower surfaceof the bed is exposed, and adjustable suspension devices which permitthe4 fuel basket to be lowered in close proximity to the surface ot' thepavement, orraised to clear ridges of the pavement in transporting theapparatus, substantially as set forth.

2. In an apparatus for repairing'asphalt pavement, the combination witha supporting frame composed of larched side bars and transverseconnecting bars, of` rear support ing wheels, a front steering Wheel, afuel basket arranged betweenv said front and rear wheels and having aperforatedbottom,transverse shafts journaled on said supporting frame,and suspension chains connecting the fuel basket with-said shafts,substantially as set forth.
